Adiabatic process

An adiabatic process is a thermodynamic process where heat is not passed into or from the liquid. This heat instead makes small clouds in the container.

Adiabatic cooling is the energy exchanged when clouds form. For example, the hot air rises (because it is less dense and is moving faster) and the cold air sinks (also because the cool air typically contains the ice crystals, which are brought closer to the Earth thanks to gravity).
